Enabling Service Connection for Virtual COM Ports
Two parameters must be set in order for a virtual COM port to allow
service access:
1. Service connection enabled
2. Passive connection: Accept incoming.
Enabling Physical Connection
The physical connection used for an incoming service connection can
be either an Ethernet or a dial-up link.
Ethernet
If the setup is using the Ethernet Communication Module DSE101, you
can establish a physical link for external access as described below:
1. In the Communication interfaces view, select your interface.
Ethernet interfaces are named ethX, for example, eth1.
2. Set the value of the parameter autoinit to Yes. This setting
automatically starts the Ethernet connection when the QML logger
is started.
Dial-Up
Setting up a dial-up link, that is, using a modem or null-modem
connection, requires setting up a dial-up network connection.
As parameters for outgoing and incoming dial-up connection are
usually different, it is necessary to create a separate communication
interface for the incoming connection. In Lizard's Communication
interfaces view, create a new interface with the settings presented in
Figure 124 on page 273 :
NOTE These instructions apply when using PSTN or GSM data call as the
carrier. Using GPRS or a similar packet switched connection for
remote service purposes is not discussed here, and is most likely a
topic to be solved with the cellular network operator. The service
connection requires obtaining a known fixed IP address for the
weather station.
